soLDEmNGI-IRON.

Be itfknown thatI, `WILL`IAM F. RYAN, a

` citizen ofthe UDitjedQStatesof America, and

resident of," Cincinnati, county of Hamilton, State of Ohio, haveinvented certain new and useful Improvements in `Soldering-Iron, oi

` l which the following is a spectOL My invention relates to a soldering-iron of l l thecharacter shown and described in the application I'iled inthe United States Patent n .Office `upon December 2, 1903, vSerial No. 183,455, by myself and NeilA. Sullivan.

2 The `object of my present invention is to provide a means whereby the oil is fed read- 1ly to the burner regardless of the osition in which is provided with a ready means forkeeping the 1,.: oil-passage free from clogging.

the upper tapered end c2 of the rod snugly in contact with the seat b.

Rod Ollas a central channel c3 extending into the collar c, which communicates with a channel c4 in a curved tube c5, which is tapped into the collar c atone end, the other end being tapped into a tube c, within which is seated adrotating coupling E, which has a beveled stud e, seated in end c7` of the tube c6 and seated on the other side against Aa spring-pressed `disk e. Coupling lL vhas a channel e2,- which communicates at one end with channel ciand at the other 'end with a t channel d in the tube D, which is tapped into coupling E and carries a weight d at its other end. Tube c is cut away at cs to per- `mit the tube D to have a revolution through an angle to `permit the weighted end thereof to pass from the bottom to the top b of the reservoir, A when the sameis inverted. Extending from a diametrically opposite `point of collar c from that at which tube c5 is secured to it is a curved arm c", upon the end l Weight 01 assists weight b in causing the rod O to rotate, so

Vthat the end of the tube D is upon the side of lthe reservoir A toward the ground, so that when held in a position such that the length of the burner is horizontal or slightly inclined to the horizontal end of the tube D always remains in the oil. `When the reservoir is inverted, so that it isat a higher point than A the solderiiigftip, the 'revolution of the tube D about the sleeve c causes the endof the tube D to follow the travel of the oil, so that in whatever position the reservoir may be the end of the tube automatically retains itseli1 in the oil to lead `the same into the channel c2.

Casting B has two arms 52123, which terminate at their upper end in a disk b4. Arm b3 has a channel b5, which communicates with channel c2 and at the upper end communicates with a ehannelf, left between tubes F and G, which are secured at their lower ends to disk b4. vaporizerH, which has arms `71, and 7L upon opposite sides, Within which are formed Tube F at its upper endis secured to a IOO chambers h2 h3 -and which has a central. Y

needle-valve seat hlt. Tube G stops below the upper end of the tube F, Withinwhose upper end is seated a removable plug M, w

ch has contracted longitudinal grooves 'm 'm' upon its sides, which register with the of tube G and has a central channel 'm2,

which registers with the channel in tube G, through which a needlelvalve stern Q ektends upward through the plug and against the needle-valve seat In, the lower end or the.

stem O receiving a thumb-screw O', which stands between the arms b2 b3.

The arms h h terminate in a ring h4, which is encircled by a split tube R which has lugs r r adjacent to each of the edges to receiver screws r2 r3, the lower to clamp' the tube R to ring h4 and the upper to clampthe soldering-tip S in place.- Over the end or needleseat It is a burner T Surrounding the tube F and vbetween casting B and vapor-chamber H is a perforated sleeve "I, by which the operator may hold the iron;

The operation is as rollows After the airressure has been placed upon the oil in the tank the needle-valve is opened, and a small amount or oil drops into the ignitioncup h5, where it is ignited. The heat or' the naine vap'onzes the oil in the chambers h2 ha, and the heat is conveyed to theplug M. The size of the grooves m m is such that after the heating has commenced nothing but vapor Will pass up through these grooves. and the heat in the chambers h2 hf* superheats this vapor, so that the combustion'at the burner D is erlicient. the grooves m m', itmay readily be accomplished as follows: The pressure in the reservoir A is released iirst by opening the valve b, which allows the pressure to be lowered through port o7. Then the vapor-chamber H is removed from thetube F, andthe plug M may be taken out or the end of tube F for the purpose of cleaning it. Should it be desired to use the iron as a blower, the tip S is removed, and a burner N, which consists or nat rings 'n n', coupled by a vertical wall n2, is placed upon the upper end or the tube R, the ring n being or a size to pass within the tube and the ring n of a size to rest upon the top thereof. Ring n has a series or holes 'n3 placed in it, and wall n2 has a set of perforations n4. When the iiarne is directed up through casting N, the air enters through perforations 'n3 and n4 and tends to make the conbustion more perfect. y

In Figs. 7 to 12 I have illustrated the preferred form or fluid-channel. In this form the disk b4 or the casting B has a central screw-threaded perforation, which receives the lower end bf of the casing b9, "whose upper end blo is internally screw-'threaded to receive the lower end or tube F', which at its upper end is coupled to the vaporizer H. Tube F has at its upper end an internallyscrew-threaded collarf and at itslower end a pluga, in Which is a groove Casing b9 has a central portee, which communicates with oil passage b5. Extending centrally through the casing b9 and the tube F is a Should it be desired to clean valvelstem 02, which at its upper end is splined to the needle-valve o3. Needle o? is externally screwLthreaded to 'engage the internal screw-threads or collar f5, the screwthreads being cut away upon side 6 to form a small passage for the vapors from tube F into the vaporizer H. The advantage of v:making the needle-valve o3 and the stem 02 in' two partsvis that they haveY a certain amount of play relatively to each other, which enables thelneedle-valve to obtainta nrm seat. casing 59 is a disk e172, which has a perforation 614 to passl through the stern 02 and perforations '1213; Disk B12 is seated against the port bu; Upon the disk Z212 is a leatherwasher 515 and a metal Washer b1, bothl or whose diameters* are of slightly smaller diameter than the interior of casing b9 and against which aiceiled spring 517 bears, the upper end of the spring bearing `against the plug f 3. The pressure of the oil through passage b5 oauees it to v'pass through 'perforations 1213 lto raise washer 515 and to pass theme op into the easing b9 and then through groovejf4 into tube yF3 where Ait is heated and passes as a vapor through opening f6 into' the vaporizer. An excess of back pressure in the tube F would carry the disks 615 and bw ii'mly'down against'the disk i712, closing the perrorations 513 and prevent the vapors from forcing yitself bf'iek into the reservoir. This effect is respecially advantageous when the iron is inverted, as it is in this position that the vapor has a strong tendency to return into the reservoir. At the lower end of the valve-stem is a packing-'nut 04. The packing Within this nut may be readily replaced by siinply unscrewing the nut and the valve-stem, allowing them to descend a short distance below the extension bs. The advantage or the screw-threaded needle-valve is that the screw-threads continuouslyclean out the exit of the collar, and thus the passage f, formed by the flat side or the screwthreadedv portion, never becomes clogged;

What I claim is'- I l. The combination of an oil-reservoir, la channel leading therefrom, a rod journaled revolubly within the reservior, and having anon-passage Within it communicating with the channel, a feed-tube secured at one end to the revolving rod communicating Wi h its channel and weighted near its other end.

2. The combination of an oil-reservoir, a channel leading therefrom, 'a rod journaled revolubly within the reservoir and having an 'oil-passage through it communicating with the channel, a'jointed feed-tube secured at one end to the revolving rod and communieating with the channel, a rotating coupling located at the joint ofy the feed-tube anda weight upon the end or the tube to cause it to rotate about the rod and about the joint.

3. The combination of an oil-reservoir, a central projection upon the bottom 'or the IOO reservoir, a central longitudinal rod jour- `naled between said projection and the toplof the reservoir, a channel leading from the 4top ofthe reservoir, a passage through the rod communicating With the channel, a feedtube secured to the rod at one end communicating with its passage and having a weight near its other end to cause the rod to revolve to keep the feed-tube in the oil as the reservoir is turned. y

l 4. The combination of a reservoir having a central projection upon its bottom a rotating rod journaled between the projection and the top of the reservoir and having a passagecomrnunicating with a passage leading from the top of the reservoir, a jointed `feed-tube connectedto the rod and communicating with .its passage and a rotating `coupling at the joint of the feedtube, and a `weight uponithe end of the viced-tube to WILLIAM F.
